Yes I have - a very similar situation. It did not end well for me particularly, in fact I posted about it on here asking a similar question to you and was told by posters I was being bullied. She escalated her campaign culminating in making public accusations about me (untrue) in a meeting, and spreading rumours of my incompetence.
Luckily for me there were a few things I’d done / did:
I’ve always been good at my job, meeting deadlines, reputation etc. This made her campaign less believable;
I confided in my line manager in an ‘off the record’ context explaining I was worried she was beginning a campaign of bullying. At this point there was little evidence but after it escalated, I was glad I’d spoken to him;
I never ever ever rose to what she did. I would have loved to confront her but it was more important to me that she was seen as the aggressor. I will at some point follow this up and let her know what I think of her, but I’m not sure how or when yet;
I kept going in. No days off sick, nothing impacted my performance (very difficult);
I strengthened other relationships in work and froze her out (blocked on social media etc). I also deleted all WhatsApp correspondence in case she decided to try and twist my words from past conversations;
Eventually I confided in my SLT. My boss is very much on my side and they protected me. She has history of this with other people in work. I’m not sure what she has on everyone but I suspect there’s something HR-related that makes her untouchable.
Ultimately I will leave because of this, but I’ll jump when it’s the right time for my career. I’ve just tried to lesson her impact on me and hope her behaviour is apparent to others and karma comes for her eventually
